Biochemistry degree or Psychology degree

Hi, I'm currently a student at Southampton University, and I completed first year in Psychology. I have a friend who goes to Nottingham who I visited at the beginning of my first year and ever since then, I've had doubts about my course/uni/both. I did Chemistry, Biology, and Psychology for A Level and got A* in Psychology, A in Biology, and 1 mark off an A in Chemistry (so annoying!). I really struggled with Chemistry theory (although that might be because I tended to leave learning/revising it until the day before), enjoyed and was mostly good at Biology, and found Psychology the most interesting and I was the best at it, hence picking it as my degree. However, I'm not so convinced about careers in Psychology as I'm not too into the whole working with patients thing, but also it just doesn't tend to pay the best. So, especially since I've had doubts since the beginning of my first year, I decided to research other options and stumbled upon Biochemistry. I seem to like the idea and the career options match what I have in mind much more (for instance, neuroscience, chemical analysis, pharmacy, forensic science) are all careers I find more interesting than psychology careers. But, my issue is since I already completed a year in Psychology and actually really enjoyed it, did well, and found it interesting, do I sacrifice that for Biochemistry?
